Traditionally the day has meant planting a tree, trimming some bushes, maybe even a stroll through the woods or a visit to a park. But in 2018 it’s time to join the fight against pervasive pollution. Pollution that’s slowly, but inarguably, threatening this country’s -- actually, the very planet’s --- future.
